ROTARY MOTOR FOR DRIVING TOOLS.

Specification of Letters Patent. P te ted J an. 11, 1916.

Application filed May 22, 1914. Serial No. 840,337.

To all u'lmm it 271((1/0077667'71.

Be it known that 1. Emma E. HAUER- a citizen of the- United States, residing at Springfield, in the county of Clark and State of Ohio, have invented certain new and useful Improvements in Rotary Motors for Driving Tools, of which the following is a specification, reference being had therein to the accompanying drawings.

My invention relates to rotary motors and more particularly to a rotary motor for driving tube cleaners that is adapted to travel through a tube with the cleaner, although it may be used for other purposes.

The object of my invention is to provide a simple, strong and efiicient motor to meet the conditions of a very severe service. To avoid joints which are liable to be jarred loose I have provided a supporting body having heads at its respective ends formed integral therewith. This affords a very rigid construction of great endurance and reduces the motor to a simple form of few parts.

\Vith these and other objects in view my invention consists of the constructions and combinations hereinafter described and set forth in the claims.

In the accompanying drawings which form a part of this specification Figure 1 is a longitudinal section of a motor embodying my invention. Figs. 2 and 3 are crosssections on the lines 2-2 and, 33 respectively of Fig. 1 and Fig. 1 is a longitudinal section showing some modifications.

, Like numerals represent the same parts in the several views.

In the drawings 1 represents a supporting body with enlarged ends preferably integral therewith forming heads 2 and 3. This affords a very rigid construction to meet. the conditions of the very severe service for which the motor is particularly designed.

,Ihesi 1pporting body and heads have a central bore or opening which-extends from a l110t()1';Gl1ilInb61'-l3 formed in the front head, through said body and the rear head 2, said rear head beingscrew-threaded at at to attach a supply conduit. An opening 5 through the wall of the body, in therear of 1 a cross-partition 6., admits the-motive agent to an annular chamber 7 formed about the body by a cylinder 8, which may be secured in any suitable way; but is shown as being screw threaded at its rear end to the head 2 and tightened in place With its front end against a shoulder 9 of the head 3. Said shoulder 9 preferably has an inclined portion 10 and the front end of the bore of the cylinder has a like inclination so that when tightened against the same it will b'e-more securely held in place. I

A. rotary motor member 11 which is shown in the form of a turbine having buckets 12 operates within the motor chamber 13 formed in the head 3. the motive agent being admitted thereto from the annular chamber 7 by ports or passages 14: that extend through the rear wall of said head. Said rotary motor member 11 is keyed upon a shaft 15 by a key 16 and istightened against a shoulder 17 on said shaft by a nut 18 on the screw-threaded end 19 of said shaft, said screw-threaded end also forming the means of attaching the tool to be driven. Said shaft is journaledwithin the central bore of said fronthead and body in front of the cross-partition -6 and a removable bushing 20 is preferably provided which may be secured in'place in any suitable way, but is shown as screw-threaded at 21 to the body, cross-slots 21 being provided for: the engagement of a tool to screw the same in place. Said shaft is provided at its rear end with a flange 22 which bears against the rear end of the bushing 20 and takes the forward thrust of the rotary motor member.

Provision is made to lubricate the shaft either by the motive agent or by oil as may be desired. The motive. agent is introduced through a longitudinal passage 23 in thecross-partition opening into a conduit 24: in the shaft which in turn opens to the bearing by cross-conduitsj 25 and a recess 25 is provided to aid in the distribution of the lubricant. 'lhesupporting body 1 is provided with an enlarged portion. 26 having an oil' reservoir 27 therein with a cross-passage 28 o )enin into the lon itudinal )assa e 23.-

This passage 23 is enlarged and screW-- threaded at its-outer end and is provided with a plug 29. A supply opening ,for'the reservoir is closed by removablescrew SO. It will be seen thatwhen oil is supplied to the reservoir-and. the plug 29 is in, place the oil. will. flow to the bearing; .and that by removing the plug 29 the motive agent will be introduced to the bearing. An opening made in the shell of the reservoir to drill the passage 28 is closed by a plug 31.

' In Fig. at an anti-friction thrust bearing is shown interposed between the rear end of cesses opening through the outer Walls so' that Whenthe rings are riveted together by rivets 33 with balls 34 in the recesses the balls will project slightly beyond the outside Wall, of said rings and contact with the'end of the bushing and shaft flange 22*. In this figure a recess 25 is shown in the bushing to aid in the lubrication of the shaft. A furthermodification is shown in that the rotary motor member 11 is provided With a shroud 35.

Having described my. invention I claim 1. In a rotary motor, a supporting body having heads of greater diameter at its respective ends oneof said heads having a motor chamber therein, a rotary motor member in said chamber having a shaft journaled in said body and means to supply the motive agent to said member, said means including a cylinder screw-threaded to one of said heads and abutting an inclined portion of the other head, substantially as described.

the motive agent from said-supply opening or oil from said reservoir to said hearing as desired, substantially as described.
